How do I manage my signed-in devices?

Devices lists every signed-in device. Rename one, save it to a profile, or sign it out.

Go to Account Dashboard → Devices → Signed In. Each row shows the device, where it is, and when it was last active. You can rename a device, save it to a household profile, or sign it out. Sign Out All signs out everything. Saving a device to a profile, and signing out another device, need the account PIN.
